In oted to the link 6 and at the other end to athis portion of the track is asharp depression extending from c to b,the track thence extending on a lower level for at least a shortdistance until the clutch is actuated. At or near the lower end I) ofthis inclined portion is located a cam 18, consisting, preferably, of awedge-shaped piece located longitudinally between the rails and eitherformed of iron or faced with a steel or iron strip along its top. Thisincline or cam is arranged to contact with the depending hook 11 of thetoggle and forces the toggle up into gripping position as the carmoves'along the depressed portion of the track. The lower or frontportion of the cam may be rounded or twisted to fit the hook 11 in itslower position, if desired, so that the cam-surface will fit the-lowerface of the hook at all points in its length.

The cam is preferably pivoted at its lower end, its higher end beingsupported on a strong' spiral spring, as shown, to allow for wearing ofthe wheels or for slightly-different sizes of the wheels.

By depressing the track at the point where the clutch is engaged I amenabled to bring the clutch down over the rope and into proper positionto engage it before the clutch is actuated. To move the car to thisportion of the track, beginning at e the track may be provided with aslight grade, so that the car will travel by gravity, or the ear may bemoved by any other suitable means. After the clutch has beenautomatically engaged the track may of course extend on any desiredlevel, and as the car moves along it will lift the rope from its rollersor supports, the clutch traveling over them.

In Figs. 4 and 5 I show the arrangement for automatically disengagingthe car from the haulage-rope. This disengaging means consists simply ofan inverted cam device, which I show as consisting of an inclined angle19, the inclination of Iwhich is forward and downward in the directionof the travel of the car. This disengaging device is preferably pivotedat its lower end, and its other end may be raised and lowered by a cam20, actuated by a cam-lever 21. This lever serves to throw the deviceinto operative or inoperative position, so that the car may bedisengaged at this point or may remain clutched to the haulagerope. Thedevice 19 is arranged so that it will engage the depending hook 11 anddraw downwardly upon it as the car moves forward, thus opening thetoggle and disengaging the rope, which will drop down below the toggleonto its supports. The shape of the face 18 of the grip-block throughthe downward strain of the rope enables the rope to assist in openingthe clutch after the toggle has been moved slightly. A

The advantages of my invention result from lowering of the car so thatthe clutch will be brought in the proper position to engage the rope.This avoids any lifting of the rope into position for engagement andenables the clutch to be normally above the rope-level, so that therewill be no accidental engagement. The clutch dev-ice is simple andeasily operated and gives an eiiicient clutching action. The springthereon compensates for any inequalities in the rope and also enablesthe final locking movement of the toggle to take place. The grip isautomatically actuated and also automatically unlocked, if desired.

Many variations may be made in the form and arrangement of the grip orclutch, the car, or device for locking and unlocking the clutch, Sac.,without departing from my invention.

I claim# 1. In a haulage system, a track having a depressed portion anda car having a gripping device arranged to be brought into alinementwith the rope as the car moves down the incline; substantially asdescribed.

2. In a haulage system, a track having a downward incline, a cam deviceat or adjacent to the incline and a car having a gripping devicearranged to be brought into alinement with the rope as the car movesdown the ineline; substantially as described. 3. The combination with adrivingrope,.of a car havinga gripping device, comprising jaws and meansfor locking the jaws upon the rope, said jaws being yieldingly clampedto compensate for inequalities in the rope; substantially as described.

4. The combination with a driving-rope of a car having clamping-jaws,and means for locking said jaws upon the rope, at least one of the jawshaving a spring-backing to cornpensate for irregularities in the rope;substantially as described.

5. In a haulage system a car having a toggle device, a jaw actuated bythe toggle device, a spring-backed jaw coacting with the togglejaw, andmeans for forcing the toggle above its straight-line position to lockthe grip; substantiallyy as described.

6. A car having a gripping device comprising a toggle, a jaw actuated bythe toggle, a p

depending hook on the toggle, and, a disengaging device arranged toengage the hook and unlock the toggle; substantially as described.

7. In ahaulage system, a driving-rope, acar having a gripping device,and means for raising and lowering the car relative to the rope to bringthe gripping device into or out of alinement with said rope;substantially as described.

8. In a haulage system, a car having a gripping device, a cam device inthe track arranged to automatically unlock the grip and connections forthrowing the cam device into or out of operative position; substantiallyas described.

In testimony whereof I have hereunto set my hand.
